"Everyone goes through challenging periods in their life. That's inevitable and it's part of being human," Kerr says in Harper’s Bazaar U.K. June issue. "I feel like it's a daily process to be positive. It's something that's a choice and I have different tools, like meditation, even prayer - my grandmother taught me to pray when I was young - and just finding that inner peace."

"Well, we are very good. We speak every day," she says. "We're really close, we're going to be a family forever and we both really do love each other."

That family, of course, includes their 3-year-old son, Flynn.

"We have genuine love and respect for each other," she adds. "We're very connected and I feel grateful for that. We created something beautiful together and we both remind ourselves how lucky we are to have that. And yeah, it's good. He's a great dad. I'm lucky."

Kerr also parted way with Victoria's Secret.

"It was a big chunk of time that I wasn't able to commit to because I'm a mother," she says of her decision to no longer be an Angel. "I used to be in two different countries every single week. I made a conscious decision to shift gears. I'm very much a people-pleaser at heart - I feel that if everyone else is happy, then I'm happy - but I'm leaning the power of saying no and putting my foot down."
